The film is set in the titular California desert resort town, where Nyles (played by Andy Samberg) and Sarah (Cristin Milioti) are apathetic guests at a cloyingly cheerful wedding. Sarah seems haunted by her past, while Hawaiian-shirt-clad Nyles is terminally over it; at night, she foolishly follows him into a magical cave and gets sucked into a time loop, one that he’s long been trapped in. Nyles is happy to have someone to share his curse with, but Sarah, being new to the experience, is more motivated to find a way out.
